Q.cutting petunias back
Shall I cut my petunias way back now in the spring? They’re looking brown underneath, but there are sill blooms on the long stalks. Thank you.
What is looking brown underneath - the stems or the leaves? If your petunia plant is bushy, they may not be receiving enough light, or your plant may just be getting very mature. Petunias can be pruned anytime. You can deadhead them (https://www.gardeningknowhow.com/ornamental/flowers/petunia/deadheading-petunias.htm) or you can prune them back severely to encourage new shoots and flowers to develop.
